On 20 th May 2019 a few minutes after having switched it on and without having transmitting while the
amplifier was in RX mode on 15m I heard and see an explosion and a spark into the amplifier. The 25A wall
panel breaker switched off. That means a minimum of 60 amps short.

I put the amp on a bench, none of the two fuses (high power for 48V and low power for other voltages) was
blown!

I removed the two external black panels (needs a hexagonal key) to have a view on the whole inside of the amps. No visible damage.
